Introduction

DwC summary table. When dealing with large volume of data if initially some information about the data set in provided, it is vital. A DwC summary table is one suvh table which provides the summary of different fields in the data set based on Darwin Core vocabularies. Below is the DwC summary table for Spatial fields.

## Map from URL : http://maps.googleapis.com/maps/api/staticmap?center=-33.296719,150.490465&zoom=4&size=640x640&scale=2&maptype=terrain&language=en-EN&sensor=false
## Plot of the data

## Plot of the data with coordinate precision

## Plot of the data with coordinate uncertainity in meters

##  Bounding box of records  -54.631102 , 114.025392 ------ -11.200197 , 158.942277 
## Centre of the data set -33.2967189465631 , 150.49046501568 
## Standard deviation in coordinates 2.79075420856109 , 2.87681736289761 
## Standard distnace of points 4.00800023756571 
## Area of the ploygon formed by the coordinates 939.116949006915 
## Below is the density circle

## The expected nearest neighbour distance is 0.217230731278645 
## The observed nearest neighbour distance is 0.0208727349391461 
## The nearest neigbhour index is greater that one- 0.0960855529799434  therefore the data is clustered 
## The null hypothesis can be rejected and data is significant and not random 
## The plot for kernel density

## The bandwidth for the kernel density is
